Searching for front end file management and upload plugin (1 post)

I'm searching for a front end plugin that allows logged in users only to upload files and view files (filemanager).
I want to be able to make subdirectories (also for logged in users), and the plugin should be able to manage a lot of file extensions / types.

It would be nice to be able to edit / review / comment on files.

I think it shouldn't be too difficult, though I haven't found a good plugin that does this.
Compatibility with a cloud service such as Dropbox or FilesAnywhere is allowed, but not neccesary.
